DETAILED DESCRIPTION
[0032] The present application will be further described in detail below with reference to the accompanying drawings. Figure 1 —3.
[0033] The embodiment of the present application discloses a cement concrete pavement repairing structure.
[0034] With reference to Figure 1 , Figure 2 and Figure 3 , a cement concrete pavement repairing structure comprises an original cement concrete road section 1, a repaired cement concrete block 2 is arranged on the original cement concrete road section 1, and a repairing support mechanism 3 is arranged between the repaired cement concrete block 2 and the original cement concrete road section 1, wherein the support mechanism comprises a repairing groove one 31 arranged on the original cement concrete road section 1, a repairing groove two 32 arranged on the original cement concrete road section 1, the repairing groove one 31 and the repairing groove two 32 are communicated and are in a ladder shape, and a support assembly 33 is arranged in the repairing groove one 31.
[0035] When repairing the original cement concrete road section 1, the area to be repaired is determined, and then a repair groove 31 is cut out on the original cement concrete road section 1 using external cutting equipment. Then, a repair groove 32 is opened on the basis of the repair groove 31. The surfaces of the repair groove 31 and the repair groove 32 are then treated. The repair support mechanism is placed in the repair groove 31, and then the mixed concrete is poured into the repair groove 31 and the repair groove 32 to form the repair cement concrete block 2. Finally, curing is carried out to harden the repair cement concrete block 2, thus completing the repair of the original cement concrete road section 1. By opening the repair groove 31 and the repair groove 32 in the damaged area of the original cement concrete road section 1, and then using the repair support mechanism 3 to support the poured concrete to form the repair cement concrete block 2, the repair cement concrete block 2 can have strong strength, reducing the possibility of insufficient repair strength.
[0036] Reference Figure 2 , Figure 3 and Figure 4 The support component 33 includes several support wires 331 set in the first repair groove 31. The second repair groove 32 has two fixing grooves 332. The fixing grooves 332 are opened on the original cement concrete road section 1. The two ends of the support wires 331 are set in the corresponding fixing grooves 332.
[0037] In addition, a contacting inclined block 333 is provided in the fixing groove 332. The inclined surface of the contacting inclined block 333 abuts against the edge of the fixing groove 332, and the contacting inclined block 333 corresponds to the supporting metal wire 331.
[0038] After repair groove 1 31 and repair groove 2 32 are prepared, prepare several support wires 331. Then, bend both ends of the support wires 331 so that they are placed on repair groove 1 31. Then, insert the bent ends of the support wires 331 into the corresponding fixing grooves 332 for temporary support. After placing the support wires 331, insert the abutting wedge block 333 into the fixing groove 332. The inclined surface of the abutting wedge block 333 abuts against the edge of the fixing groove 332. The abutting wedge block 333 is gradually inserted. During the process, the anti-interlocking inclined block 333 abuts against the fixed support wire 331 to keep the support wire 331 stable. Then, concrete is poured to form a repair cement concrete block 2 in the repair groove 1 31 and the repair groove 2 32. The repair cement concrete block 2 wraps the support wire 331. By laying the support wire 331 between the repair groove 1 31 and the repair groove 2 32, the support wire 331 is poured into the repair cement concrete block 2, thereby enhancing the integrity of the repair cement concrete block 2 and reducing the possibility of damage requiring repair again.
[0039] Reference Figure 1 , Figure 2 and Figure 3 Polyurethane fibers are added to the repaired cement concrete block 2. When mixing the concrete to be poured, polyurethane fibers are added to the concrete to ensure that the polyurethane fibers are fully mixed with the concrete. By mixing the polyurethane fibers with the concrete, the strength of the repaired cement concrete block 2 can be further enhanced when it is poured into the repaired cement concrete block 2, reducing the possibility of breakage.
[0040] Reference Figure 2 , Figure 3 and Figure 4 Several evenly distributed stabilizing grooves are formed on the inner wall of the repair groove 31. After the repair groove 31 is formed, evenly distributed stabilizing grooves are chiseled on the inner wall of the repair groove 31. When pouring concrete, the stabilizing grooves increase the contact surface and friction with the concrete. By forming stabilizing grooves on the inner wall of the repair groove 31, the stability of the connection between the repaired cement concrete block 2 and the original cement concrete road section 1 can be enhanced.
[0041] Reference Figure 2 , Figure 3 and Figure 4 A metal mesh 4 is installed inside the repair groove 31, and the metal mesh 4 is in contact with the bottom of the repair groove 31. After both repair groove 31 and repair groove 32 are opened, they are cleaned. Then, the metal mesh 4 is laid directly in the repair groove 31. When the concrete is poured, the concrete wraps around the metal mesh 4. When the concrete forms the repair cement concrete block 2, the metal mesh 4 further strengthens the integrity of the repair cement concrete block 2. By laying a layer of metal mesh 4 at the bottom of the repair groove 31, the strength of the repair cement concrete block can be further enhanced.
[0042] Reference Figure 2 and Figure 3 Both the inner walls of repair groove 1 (31) and repair groove 2 (32) are coated with a waterproof layer, which is a waterproof coating.
[0043] In addition, an adhesive layer is provided on the waterproof layer, which is an epoxy resin solution.
[0044] After repair trench 1 (31) and repair trench 2 (32) are prepared, waterproof coating is sprayed into them to form a waterproof layer. Then, an epoxy resin solution is applied to the waterproof layer before concrete is poured. By using the waterproof layer to waterproof repair trench 1 (31) and repair trench 2 (32), and by applying an adhesion layer on top of the waterproof layer, the seepage of water from the foundation of the original cement concrete section 1 can be reduced, thus reducing the impact on the quality of the repaired cement concrete block 2. Under the action of the adhesion layer, the integrity between the repaired cement concrete section 1 and the original cement concrete section 1 can be improved.
[0045] Working principle: When repairing the original cement concrete road section 1, the area to be repaired is determined, and then a repair groove 31 is cut out on the original cement concrete road section 1 using external cutting equipment. Then, a repair groove 32 is created based on repair groove 31. The surfaces of repair grooves 31 and 32 are then treated. Evenly distributed stabilizing grooves are chiseled into the inner wall of repair groove 31. Waterproof coating is then sprayed onto repair grooves 31 and 32, followed by an adhesion layer. A metal mesh 4 is then laid directly at the bottom of repair groove 31. Finally, the ends of several supporting metal wires 331 are bent to allow the supporting metal wires 331 to... The support wire 331 is installed on the repair groove 31. The bent ends of the support wire 331 are then inserted into the corresponding fixing groove 332 for temporary support. After placing several support wires 331, the abutting insertion wedge 333 is inserted into the fixing groove 332. The inclined surface of the abutting insertion wedge 333 abuts against the edge of the fixing groove 332. As the abutting insertion wedge 333 is gradually inserted, it abuts against the fixed support wire 331 to keep the support wire 331 stable. Then, concrete is poured to form repair cement concrete blocks 2 in the repair groove 31 and the repair groove 32, thus completing the repair of the original cement concrete road section 1.
